Re: Remove_SMM... UEFI.
Since I did get a 2x5 beeps and a black screen on my l560 test system lenovo had won. I bought a used motherboard without a SVP for 160 US$. The first thing I did was to deactivate Computrace.
I learnt
- how to read/write from the UEFI bios chip using SOIC-8 hardware,
- how to identify addresses in UEFITool_0.28.0_linux_x86_64 or UEFITool_NE_A57_linux_x86_64
- how to read/edit HEX files and it's addresses using Bless,
- how to compare HEX files using Meld
- how to replace a motherboard (I did not know how tiny fingers you need)
I did not learn how to patch an UEFI bios on my own because provided files did not work or documentation is limited/not detailed enough. Since I do not know what is added to the UEFI bios if I provide any bin dump here I will be happy to not having done so. Security for my system is crucial.
Applying reverse engineering techniques with e.g. IDA Pro to proprietary software from Lenovo is interesting but it costs so much time. Next time I will check if laptops are compatible to open source bios's (e.g. coreboot or libreboot) which I will prefer. Unfortunately l560 is not supported right now.
I hope that Lenovo will allow open source bios's in the future. If not customers will change their consumption like me.
Anyway thank's for trying to help!
Hasta luego!

Hey everyone!
I need help with my Lenovo Chromebook 100e Gen 3.
Here are the details:- Motherboard: LA-L131P
- MFG Date: 2022/01/07
- MTM: 82J80001BR
- MO: MPNXB2103001
- Factory ID: LI123
I bought a new Winbond 25Q128FVSG chip.
The chip currently on the board is the same model but with different ending letters.
I can’t use the CH341 clip on the chip that’s on the board because it’s too low-profile and doesn’t make proper contact.
The Chromebook is Google account locked, and I’ve already tried everything.
I understand that I need to replace or... -
Hi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.
For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... . Do not shut down to prevent... -

Hey guys,
Bought myself Surface Pro 4 tablet today on a local craigslist-type website.
I've seen that UEFI was password protected and of course the seller forgot the password, but decided to buy it anyway.
Really needed such a tablet to use with RomRaider to do some logging/tuning on my car.
It has secure boot turned off and boots from USB, so I've formatted SSD and have done clean win10 install.
Works fine, but wanted to ask, are there any real security risks associated with UEFI settings on Surface (remote access etc.)?
From what I've... -
Hi guys.
I am very new to this business and i have some questions. Maybe someone can help me further.
I have a 2015 Intel NUC NUC6i3SYH and for some internet and office the computer works perfectly. Lately it has been bugging me a bit on and off. Then I saw there is a UEFI update from Intel and I thought if I put it on, the problems might be gone, but unfortunately the update didn't go through. The screen stayed black and after waiting for a while nothing happened, I had to pull the plug at some point. Of course, the NUC then failed to boot!
